Comprehensive and Detailed Explanation:Use Case diagrams are included in the BRD because theyhelp analyze and refine requirements and design by providing a visual representation of interactions between users and the system.

BABOK® Guide (Chapter 10.48 - Use Cases and Scenarios)states that Use Case modelshelp stakeholders understand how the system will function without needing deep technical knowledge.

Models (Option B)do not replace text-based requirements butenhance understanding.

Models are not only for technical teams (Option C, D); they helpbusiness and technical stakeholders collaborate effectively.

According to the BABOK Guide, high quality requirements have the following characteristics1:

Atomic: Each requirement addresses only one thing and can be verified independently.

Complete: Each requirement provides all the information necessary for the intended audience to understand it.

Consistent: Each requirement does not conflict with any other requirement or source of authority.

Correct: Each requirement accurately describes the needs of the stakeholders and the solution.

Feasible: Each requirement can be implemented within the constraints of the project and the environment.

Modifiable: Each requirement can be changed when necessary and the impact of the change can be assessed.

Prioritized: Each requirement has an agreed-upon level of importance or urgency relative to other requirements.

Testable: Each requirement can be verified using a defined process or method to determine whether it meets the acceptance criteria.

Unambiguous: Each requirement has only one possible interpretation and is clear and concise.

Understandable: Each requirement can be comprehended by the intended audience without any difficulty or confusion.

Among these characteristics, the one that demands that all requirements in a set or model support its overall purpose and scope is cohesive. Cohesion is the degree to which the elements of a set ormodel are logically related and focused on providing a specific and consistent outcome2. A cohesive set or model of requirements is easier to understand, maintain, and verify, as it avoids unnecessary complexity, redundancy, and inconsistency. A cohesive set or model of requirements also ensures that the requirements are aligned with the business objectives and stakeholder needs, and that they do not introduce any out-of-scope or irrelevant features or functions3. References:
